"A man stalked the streets of Toronto, a 45-year-old mother of four in his sights."

"He mapped her movements through her downtown neighbourhood, plotted his attack, then savagely struck one August night in 1983. When he was done, Susan Tice lay sexually assaulted, stabbed and breathing her last in her own bedroom."

"Four months later, the scene played out again, this time during the Christmas rush in the heart of Yorkville — one of the city’s most posh neighbourhoods. The victim, 22-year-old aspiring fashion designer Erin Gilmour, suffered the same horrific fate."

"That’s what detectives at the Toronto cold case unit believe happened. In both cases, they say the assailants left behind traces of his DNA, captured by police."

"On April 3, 2002, the Toronto Police were called in to investigate a strange smell coming from the apartment of computer salesman Michael De Bourcier. They knocked on his door and called his phone, but received no response. They were issued a warrant to investigate and gained entry to the apartment. There they discovered Michael's body - dead from what appeared to be a heart attack. At 35 years old, Michael was not the typical profile of a heart attack victim. The police took note - more investigation might be needed."

"To empower Canadian homebuyers to do their own detective work, real-estate brokerage TheRedPin recruited private investigator Dave Perry, a former Toronto homicide detective and cofounder of Investigative Solutions Network. He is regularly consulted to investigate investment neighbourhoods for a confidential roster of clients."

Dave Perry is an accomplished senior executive who has established an international reputation as one of Canada's premier investigators. As a result of a distinguished, 27 year career with the Toronto Police Service, Dave is called upon regularly, by various media outlets to provide expert opinion on domestic and international cases. He has been sought out by the private sector and law enforcement and governmental agencies, worldwide, to conduct seminars on investigative strategies, interviewing techniques, and major case management.

"David Perry has been investigating sex crimes for more than three decades, first as a Toronto Police officer, now as a private investigator. Even with all that experience, watching and listening as victims re-live childhood sexual abuse never gets easier."

"The 58-year-old Montreal man who had been sitting across from me moments ago has disappeared. In his place sits a preteen boy, re-living a nightmare that started decades ago, back home in Saint John, New Brunswick."

"The digital age can be a hindrance when it comes to probing someone's past, says Ron Wretham, one of the chief executive officers of Investigative Solutions Network Inc. "With the proliferation of the Internet, people are able to purchase false documents like high school diplomas, university degrees""

"The discovery in a Cleveland residence of three women who had been missing for a decade has many people wondering how it’s possible they were confined so long without anyone knowing. Dave Perry, a former detective with the Toronto Police homicide and sex crimes unit, shares his insights."

"Perhaps the best way to determine how you want to be perceived as an interviewer is to ask yourself this question. What kind of an interviewer would you want to be questioned by and how would you like to be treated? Regardless of the situation, would you prefer an angry, aggressive interrogator using methods that would be ruled inadmissible in most courts? Or a skilled, well spoken interviewer using rapport based systems that fall well within the Canadian Charter of Rights and Freedoms. I firmly believe that the word interrogation and most of the techniques associated with it by definition have no place in the Canadian interview process. "

"Private investigators have identified more than a dozen new victims of a former police sergeant who was already convicted of abusing children while he was on the job."

"David Perry, a former Toronto police detective now leading the Saint John investigation, is working with a $100,000 budget as he and his team continue their search for victims of Kenneth Byron Estabrooks, who died in 2005,and offerthem support."

" Kenneth Byron Estabrooks is shown in 1999. The former Saint John police officer showed no remorse for sexually assaulting three boys and a girl, one of whom was just five years old during the time of the abuse, court documents show."

"SAINT JOHN –A man who was molested by a former Saint John police officer when he was just seven years old says he is still haunted by the cruel abuses he suffered so many years ago. Those chilling memories, the nightmares, never go away, he says."

"And now, as private investigators seek out more victims of convicted child abuser Kenneth Byron Estabrooks and offer them counselling, this 60-year-old man says city officials never showed any concern for his well-being during the criminal trial or in the years after ward."
